Hello,

Thank you very much for shopping with us. You are right - the demand for cryptocurrency and hardware wallets (especially Ledger Nano S) are stronger than ever, and we are soon going to stop taking the pre-orders for the early July shipment.

Not sure about pennywise, but I've ordered my third Nano S thru https://coinzin.com

It was S$99, now S$105. Looks like demand is stronger than ever.

I expect my delivery to be around late June/mid July at this rate.

No; delivery outside of Singapore is not included in the price. Delivery to Peninsular Malaysia using a courier from S$7 (East Malaysia is more expensive). We were previously using registered mail, but we believe we found a faster option.

Your S$105 price is inclusive of delivery to Malaysia?

From my experience, ShapeShift is more expensive (the commission, exchange rate, etc). Also, I generally don't trust third party wallets online. There are a few 'scam' wallets on Apple App Store, which look very sleek, but which others have raised red-flags.



QUOTE(denimblue @ Jun 7 2017, 02:22 PM)
Hold on.....

Does that mean I don't need to use an intermediate exchange like Poloniex to convert my Bitcoins to ETH?

The built-in Shapeshift in Exodus will do the conversion?

I was searching for a better (or best) option to store my beloved cryptos, and found Ledger Nano S.

I only sell what I use personally for myself. I don't even trust some of the exchanges - e.g. see Mt Geox.

I would say what people have said to me before - before I got my first Ledger Nano S (I did a lot of research before choosing Ledger Nano S):

1. If you have more than US$1,000 in crypto (or expect your coins to appreciate more than that amount), get a hardware wallet or a paper wallet. For me, a paper wallet is tough to manage (especially if you trade) and I would like an easy integration such as with MEW [the real MEW].

n.b. Even if you have Ledger Nano S, it does not support all coins, such as Lumens, and Waves. Ledger SAS is adding more coins (they just added Ripple a few weeks back). The current list of supported cryptos is: Bitcoin; Ethereum / Ethereum Classic (use MEW to access Ethereum alt coins like Golem, Gnosis, BAT, etc); Ripple; Litecoin; Dogecoin; Zcash (z-addresses are not supported); Dash; Stratis. Monero is expected to be added next.

2. You may have to use online exchange accounts one way or another and you must keep such accounts safe as well. Please use a two-factor authentication (such as Google authentication) if the exchange supports it. Most reputable ones do. An online customer told me just yesterday he lost quite a sum because his exchange account got hacked (stolen password). He did not use two-factor.

3. Even if you exchange account is secure, they are prone to mass hacks (see Mt Geox), DDOS, mismanagement or fraud (those dodgy ones), etc, so it is dangerous for your cryptos to be in the exchange. For me, if Ledger Nano S supports the coin, I will transfer the crypto immediately to the device after a trade. I trust in my Ledger Nano S a lot. I worry for my cryptos still left at the exchange (e.g. Lumens) and hope Ledger SAS will support it soon.

4. BUT Even if you have Ledger Nano S, please keep your 'seed' very very very very safe (I cannot emphasize enough). Even if you lose your Ledger Nano S, you can backup using the seed. So if you lose your seed, and you lose your password or Ledger Nano S, you lose it forever. It works like a double edged sword; if someone gets hold of your seed somehow (say you email yourself with those seeds and a hacker manage to get access of your email, or you take a picture of it and save it on dropbox and a hacker hacked your dropbox, they will have access to your funds (basically they just have to backup the funds to another Ledger Nano S using that seed).

I keep my Ledger Nano S seed away from networks/internet and will never type it on a computer or mobile device. I don't even take a picture of it. It is in my safe.


My tip is: (1) Buy Hardware Wallet. (2) Keep the seed very very very safe. (3) Use a two-factor authentication for exchanges. (4) And enjoy the ride! biggrin.gif

Need a clearer understanding

If I would someday misplace/lost my Ledger Nano S, as long I have the SEED, I can still get back my coins through backup on another new Ledger Nano S after losing the old ones?


As I have not gotten my Ledger Nano S, the SEED is actually the password?
*
Yes for the first question. No for the second question.


Seed on ledger nano s is recovered through a 24 words backup. It is not password to the device, but more like a encrypted master key.

If you enter the password wrongly three times of ledger nano s, your device gets reset/wiped. You need to enter the 24 word to recover your wallet. If you lose the 24 word, or if another untrusted person has the 24 word, you lose your wallet.

He should NEVER give out the seed (unless you really trust the person)

We went from being amazed at raising US$5,500,000 under 13 hours last year to expecting future ICOs to raise US$36,000,000 under 30 seconds like BAT just a week ago.

oh yeah just wait till you see how KIN does their token launch for their existing 15,000,000 userbase.
when you first plug in the ledger and it generate a super secret private key, it also prepares a 24 word backup of that same key in case you messed up, lost it, device broke down or someone stole it from you.

that combination of 24 words are no different than writing down your PIN on your ATM card and leaving it around, so it's up to your own creative way on how to split it, scramble it, and keep it safe with multiple copies in case your house/bank got flooded or burned down.

Exactly right in relation to private key and seeds.

Email support
I remembered watching a youtube video a few days ago of someone that accidentally lost his wallet and Support was requesting him for his recovery words

Don't give the support your seed or 24 words - do it yourself! Also I don't know how support can access your new ledger device and restore for you without physically being there - as far as I am aware, that is not possible.

how does the new ledger devise recognise my old backup number? meaning there is a chip that stores all customer's SEED in the system?

meaning there is still way to hack the system to get those customer's SEED and buy a new devise to get into that private key to the coin and withdraw it by hackers?

laugh.gif   

yup, another question from me

I am not an expert in crypto. Please let me share my limited knowledge.

It is crypto-sequence, for Ledger, you enter the 24 words, you get a specific key. 12 words from electrum's dictionary contain 256 bits of entropy, the same strength as ECDSA which underlies Bitcoin. Ledger uses 24 words compared to Bitcoin. 'Easier' to hack Bitcoin and get your billions first.



If you enter a 'wrong' 12 or 24 words, you get a different key (which would be useless and empty, because the probability of you matching another person's 12 or 24 words is infinitely small - see the following - (basically at 1000 guesses per sec, it will take 550 years to crack a specific wallet for a 4 word device - imagine how long it will take for a 12 words or 24 words - it is not x12 or x24 but exponential):

So sure, you can take a shot and enter a random 12 word or 24 word. This will allow you to have access to some wallet, which in infinite probability be new and empty. Unless your 12 words or 24 words are not random and created by you - e.g. the 12 words are all apple, apple, apple, apple, apple....

You can always create your own words from random dice rolls from the words in the dictionary if you like. You do not have to use the ones given when you set-up/start the device.

Some of the whales are collective groups, who are going to use crazy amount of gas - in a way, this is economical because they are sending a lot of ETH and they will get priority processing because of the amount of gas used.

Tried withdrawing from Poloniex and I found it has to go through a few stages. Why would one say it is not secure?

i) log-in needs 2FA
ii) withdrawal also needs 2FA
iii) need to log-in email to confirm

How insecure is this? The hacker has to get 2FA codes twice and to be able to log-in the email to withdraw.

Should I HODL onto BAT or should I cut loss, what would you do? There isn't much news about it hence it dips like the rest since everyone is hopping into ETH
Comments are appreciated wink.gif

I was in the same position as you. I was holding and it keeps bleeding. I cut loss and invested to Ether right before the recent jump.

Mid to long term BAT should rise, but probably ETH would rise more. My 2 cents.

amazing revelation by TenX team, they actually work closely with MAS (Singapore Central Bank)

how much more legit can they get?

also there's a pre-sale starting tomorrow, cap of 100,000 ETH, minimum 125 ETH to participate

email julian@tenx.tech to be added into the waiting list, in case some FFK.

meaning 100,000 ETH left for ICO peeps.

Fun video, show this to doubters that claimed crypto can't be spent as money

125ETH min.. what they smoking?
